IMPROVEMENT` IN STOVE-PLATFORMS.

Specification forming part of Letters Iatent N o. 177,600, dated May 16, 1876; application tiled May 1, 1876.

To all whom it may concern:

Beit known that I, WILLIAM WEsTLAKE, of the city of Chicago, Cook county, State of Illinois, have'invented anew and useful Improvement in Platforms for Stoves, of which of the metal is such that itis easily bruised and bent. To support the metal an interior ofwood has been used; it answers the purpose well, but involves considerable extracxpense. v

The object of my invention is to make a platform for stoves of sheet-zinc, which shall have an edge which will not warp or turn up in use; and v.this I accomplish by providing the platform with a verticaledge about threeeighths of an inch,- or 'onehalf of an inch, in

width, strengthened and supported by the4 insertion of a hoop of iron, as hereinafter more fully set forth.

In the drawings, Arepresents a completed board. The main and central portion a 1s lshown flat, though' it might be corrugated near the center, if desired. b is a beveled edge, extending up from the main portion a at a suitable angle until it reaches a point about threeeighths of an inch, or one-half of an inch, above a, at which point the metal is turned over and then down, formingan edge,

o, which is vertical, ornearly so, to a. dis a.

metal hoop -insertedwithin the edge c, and held in place by turning the zincover, as represented at c. This hoop d must be of such size as to resist any pressure to which it is` lia-ble tobe subjected, and it will support andv strengthen the edge of the board so perfectly that it willnot warp `or spring, andwill not be bruised or injured by any ordinary use, it

' being capable of bearingthe entire weight of a person without bending or yielding. The

"lower and turned-over edge c I prefer to Inake on a plane a little below the main portlon a of the board, so that the edge will always rest upon the floor.

I have only shown a round board but' the same construction is adapted to be used with boards having round corners.

aient to stamp the metal into the form shown in Fig. 3; then the hoop can be dropped into It will be seen that the form of the completed board is such that any ashes or coals falling from the stove thereon will be caught ,and held by reason of the raised portion b.

This. construction permits the use of very light zinc.'

about fortyfive degrees to a. I prefer this form; but the angle might be more orlessindeed, might be almost a right angle, except for the diiiculty in manufacturing, and the fact that it will be much more difficult to keep the board clean. y

The central portion a of the board is designed to be in contact, or nearly so, with the floor, so that the legs ot' the stove can stand directly thereon without having any additional support. v

I am aware that zinc boards have been made ofa single piece of zinc, circular or oval in form, the edge being strengthened by a piece of wire; but such boards 'will warp or door. Ido 'not claim, broadly, a zinc board having its edge stiffened in anypossible Inanner; but i What I do claim, and desire to secure by Letters Patent, is as follows:

tral sheet a, raised portion b, and edge c, all made from a single piece of sheet metal, in

oval boards, and with square and oblong In manufacturing it will be found convenits place, and the edge c turned over to hold it.

I have shown the part b at an angle ofV spring in use, and the outer edge thereof will. not,at all times, be in close contact with the A platform for stoves, consisting of the cencombination with the hoop d, substantially as
